[PATCH 0/8] ftrace/x86: function_graph stack dump fixes

[Josh Poimboeuf]

Some stack dump fixes related to function_graph tracing.

Josh Poimboeuf (8):
  ftrace: remove CONFIG_HAVE_FUNCTION_GRAPH_FP_TEST from config
  ftrace: only allocate the ret_stack 'fp' field when needed
  ftrace: add return address pointer to ftrace_ret_stack
  ftrace: add ftrace_graph_ret_addr() stack unwinding helpers
  x86/dumpstack/ftrace: convert dump_trace() callbacks to use
    ftrace_graph_ret_addr()
  ftrace/x86: implement HAVE_FUNCTION_GRAPH_RET_ADDR_PTR
  x86/dumpstack/ftrace: mark function graph handler function as
    unreliable
  x86/dumpstack/ftrace: don't print unreliable addresses in
    print_context_stack_bp()
